This serum is a must-have for oily skin! It's extremely effective, especially when used in the morning plus at night. I've noticed a big reduction in sebum production on my skin, as well as a slight effectiveness on redness and marks. However, it's not very effective on active blemishes, and mainly helps to limit their future appearance. On the plus side, it's quite moisturizing.
